The number of the supporting legs 16 may be four, and the four supporting legs 16 are respectively located at four corner regions of the base 11 to stably support the rack 10. Of course, the number of the supporting feet 16 may be five, six or more, and the supporting feet are distributed around the center of the base 11 at intervals.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
